Preheat the oven to 350°. Split the English Muffins apart and place them on a greased cookie sheet. Cream the Pub Cheese, butter, garlic powder, and crab in a separate bowl. Spread the creamed ingredients onto the English Muffin halves. Add salt and pepper to taste. Bake for 20 minutes. Finish by broiling them for an additional 3 minutes or until they are golden brown. Let them cool and then cut them into quarters. Serve and enjoy!
